Title: Improvements in and relating to the production of tempered glass sheets
IPC: C03B27/004
Filed: 1934-04-28
Abstract: 437,123. Tempering glass sheets. PILKINGTON BROS., Ltd., Tower Building, Water Street, Liverpool, and WILSON, J., 23, Meadow Hill Road, King's Norton, Birming- ham. April 28, 1934, No. 12878. [Class 56] A process for making tempered glass sheets consists in forming molten glass into a continuous strip by drawing or rolling, cutting the strip into sheets while the glass is still plastic, and then cooling the cut and unannealed sheets rapidly to temper them. Fig. 1 shows an apparatus in which the glass strip 1, drawn vertically upwards from a bath of molten glass, passes between chains 3 which hang from chain wheels 4 driven in unison with one another. A stamping die 9 is pivoted to . each link of the chains, and pairs of dies cooperate with one another to stamp a sheet out of the strip. Each die consists of a casing 15, Fig. 3, containing a massive plate 16, one plate being sunk in its casing while the other protrudes from its casing. Thus when the plates are pressed together, they cut a sheet out of the glass strip. Further, the sheet so cut out is rapidly chilled and tempered by contact with the plates 16 which have been cooled by water sprays from pipes 14, Fig. 1. The dies are pressed together by pneumatic cylinders 27 which are suspended by chains 23. The glass strip may also be formed by rolling, the sheets cut out of the strip being cooled by air blasts in the usual way. The strip travels over a bed and passes between a pair of rollers, one of which has end flanges which trim off the edges of the strip. Transverse cuts are then made by a knife which descends and presses a narrow strip of the glass into a slot in a member arranged in a gap in the bed. The slotted member is pivoted on its support and is caused to swing by cams, so that its upper surface moves with the glass strip while a cut is being made. The sheets cut off the strip are suspended by tongs and carried between blowing- frames of the usual kind.

Title: Improvements in or relating to axle trucks for railway or like vehicles
IPC: B61D13/00
Filed: 1922-05-08
Abstract: 203,735. Boyden, G. A., and Boyden, J. C. May 8, 1922. Axle-trucks.-A railway or like car truck comprises pilot, central and trailer truck members which are articulated so that each pilot or trailer member may have an independent horizontal lateral movement and a coordinating plate rigidly secured to the car body to co-ordinate the angular position of the central member to that of either or both end members. The pilot and trailer truck members 22 are articulated to the central truck member 32 by hemi-spherical socket joints 24. The central truck frame is mounted to slide transversely of a co-ordinating plate 35 by means of a box-like structure 44 on the co-ordinating plate engaging between the side frames of the central truck member. The trailer or pilot truck is provided with projections 25 which guide the free ends of a leaf spring 40 interposed between the truck and co-ordinating plate and the housing of each of the axle-bearing springs is cylindrical, the housings lying between projections 37 depending from the co-ordinating plate so that relative transverse movement between the axle truck and co-ordinating plate is prevented. When the pilot truck enters a curved track the cylindrical surfaces 27 bear against the projections 37 of the co-ordinating plate to move the co-ordinating plate angularly about the cylindrical surfaces 27 of the trailer truck as pivots permitting the pilot truck to have a horizontal lateral movement independent of the other members. The angular movement of the co-ordinating plate 35 adjusts the central truck member angularly for entering the curved track. Specification 170,051 is referred to.

Abstract: 509,950. Fire-extinguishing. TAPPE, W. May 4, 1938, No. 13329. Convention date, May 18, 1937. Addition to 448,928. [Class 47 (ii)] The foam-discharging apparatus described in the parent Specification is modified in that the inner pipe section 1 is detachably secured to the uprights 4, as by means of a fork 22 and bolts 9. The struts 5 are rods which are detachably connected to the upper end of the uprights, the latter are pivoted to the turntable 30 by pivots 11. movable along slideways 12, and the erecting means for the pipe consists of screws 6 rotatable by a crank spindle 28 and engaging nuts 14 pivoted to the uprights. In order to collapse the apparatus for transport purposes, the fork 22 and rods 5 are detached from the uprights, and the pipe can then be moved inwardly of the turntable to a position of stable equilibrium, Fig. 3. The uprights are lowered by moving the pivots 11 rearwardly on the slideways 12. 33 is a counterweight having a central slot to receive the pipe. The nuts 14 may be readily detachable from the uprights 4. In a modification, Fig. 5, additional struts 34 secured to the pipe section 1 are united by a rod engaging in slots 35 in the uprights 4. When the pipe is moved rearwardly on the turntable, the uprights are folded down, as shown, by the struts 34, which then may be used to push the pipe further rearwardly by rotation of the screws 6. In another modification, the rods 5 are pivoted to the uprights and to a collar slidable along the pipe section 1, the uprights being folded down, after the nuts 14 have been detached, by movement of the rods 5. The outer pipe sections 2, 3 are stayed and extended by guy ropes 7 and a chain 39, Fig. 7. The ropes 7 are secured at one end to the top of the uprights 4 and at the other end pass over pulleys 38 on the section 2 before being secured to the inner end of the section 3. The chain 39 is secured to the section 3, passes over a sprocket-wheel 10 rotatable by a crank spindle, then over a loose pulley 40, and is secured to the section 1. A rope 41 secured to the axis of the pulley 40 passes over a pulley 42 secured to the section 1 and is attached to the inner end of the section 2. By this arrangement, rotation of the wheel 10 is effective to extend or retract both the sections 2, 3, at the same time keeping the ropes 7 and 41 taut so as to support the pipe. If additional pipe sections are employed, additional loose pulleys are provided. The pipe sections may be of circular or other section, and the section 3 may comprise two or more pipes joined by a web or webs, Fig. 8. In this case, separate hoses 25 are provided for each pipe-3, and also separate nozzles, which may vary in length, and may comprise check valves operative to close them in case of damage.
